Polyoxyethylene Lauryl Ether

Brief Overview

Polyoxyethylene Alkyl Ether (AEO) is a series kind of anionic surfactants and synthesized by lauryl alcohol and ethylene oxide. It is good biodegradable property has made polyoxyethylene alkyl ether is a successful substitute for nonylphenol etoxylates (NPEO) in detergent use. Polyoxyethylene alkyl ether is non-toxic, stable with acid and alkali, and soluble in water becomes worse with the rise of the temperature. Polyoxyethylene alkyl ether, as made from fatty alcohol, may react with different proportioned EO to produce versatile hydrophilic and hydrophobic surfactants, which are widely used in detergent formulations and industrial raw materials.

Manufactoring Process

The method for producing a Polyoxyethylene Lauryl Ether, which comprises: a sulfation step wherein an ethylene oxide addition product of an alkyl alcohol having 8-22 carbon atoms is reacted with an SO3-containing gas, thereby obtaining a sulfated product of the ethylene oxide addition product, and a neutralization step wherein the sulfated product is neutralized, thereby obtaining a sulfate. The ethylene oxide addition product contains from 0.01% by mass to 1% by mass (inclusive) of an alkali metal hydroxide relative to the total mass of the ethylene oxide addition product.
